PREFACE. 


This  bulletin  is  dedicated  to  the  young  people  of  Iowa.  Every 
boy  and  girl  who  has  commenced  the  study  of  botany  should  have 
&  copy  of  it.  The  bulletin  will  not  take  the  place  of  the  regular 
text-book  on  botany,  but  as  soon  as  the  student  has  become  fa- 
miliar enough  with  plants  to  analyze  them,  it  will  serve  as  a 
check-list  to  those  found  growing  in  this  state. 

This  preliminary  list  of  more  than  three  thousand  species  in- 
cludes only  the  native  plants  and  those  that  have  been  introduced 
from  other  sections  of  this  country,  or  other  continents,  and  have 
escaped  from  cultivation,  and  become  naturalized  and  are  now  a 
part  of  the  flora  of  the  state.  When  the  list  is  completed  it  will 
contain  more  than  five  thousand  species.  The  cultivated  plants 
will  receive  attention  in  a  later  issue. 

The  limits  of  this  bulletin  would  not  permit  extended  notes 
on  species,  or  synonyms ;  but  the  habitat  of  the  plant ;  the  fre- 
quency of  its  occurrence,  and  common  name,  when  known,  arc 
given;  but,  unfortunately,  many  of  the  Thallophytes  are  known 
only  by  the  professional  botanist  and  have  no  common  names. 

The  study  of  plant  life  is  world-wide,  and  botanists  of  dif- 
ferent languages  have  accepted  a  common  standard,  which  is 
still  in  use.  We  hope  the  day  is  not  far  distant  when  the  De- 
partment of  Agriculture  at  Washington  will  take  up  the  matter 
through  its  experiment  station  botanists,  in  cooperation  witli  the 
colleges  and  universities  of  the  country,  and  give  the  American 
people  an  English  translation  of  the  accepted  Latin  classifica- 
tion, then  the  study  of  plants  in  the  common  schools  will  be 
as  simple  as  any  daily  routine  in  school  work.  However,  until 
that  time  arrives,  we  must  accept  the  situation  as  it  is.  and  fa- 
miliarize our  tongues  with  these  Latin  names  as  best  we  can, 
until  a  better  system  is  evolved  for  the  use  of  the  millions  who 
will  speak  of  plants  only  in  their  mother-tongue. 

I  have  changed  the  order  of  arrangement  of  classes  in  the 


ij-3,b  71 


4  STATE    HOETICULTUEAL    SOCIETY 

Thallophvtes  from  that  followed  by  the  systematic  botanist,  who 
usually  begins  with  the  Alg*  and  then  places  the  degraded  forms 
called  Fungi,  after  the  orders  to  which  they  are  allied.  I  have 
given  more  prominence  to  their  functional  differences  than  to 
their  structural  arrangement,  and  have  placed  these  parasitic 
and  saprophytic  plants  first,  because  they  do  not  contain  chloro- 
phyll and  are  unable  to  convert  dioxide  of  carbon  into  starch 
under  the  action  of  sunlight,  which  substance  enters  so  largely 
into  the  composition  of  the  cell  structures  in  higher  plants,  but 
must  secure  this  organized  matter  for  growth  and  development 
from  living  or  dead  plants  and  animals.  This  order  of  arrange- 
ment does  not  take  into  account  any  theory  of  evolution  or  degra- 
dation, but  is  for  the  convenience  of  the  student  who  studies 
plants  only  from  an  economic  standpoint,  to  have  those  of  a  sim- 
ilar habit  grouped  near  each  other.  We  have  placed  the  slime 
moulds  first,  though  they  are  not  the  least  in  size,  but  are  cer- 
tainly low  in  the  scale  of  organized  matter.  Botanists  have  often 
been  in  doubt  whether  they  belong  to  the  animal  or  vegetable 
kingdom.  Next  in  order  are  the  bacteria ;  among  these  are  some 
of  the  smallest  vegetable  organism,  but  with  a  good  microscope  we 
can  find  them  in  almost  every  substance.  They  live  in  animals 
and  plants,  often  causing  troublesome  diseases,  which  sometimes 
prove  fatal  to  the  animal  or  plant  attacked.  They  are  in  the  air 
we  breathe,  the  water  we  drink,  and  the  food  we  eat;  they  live 
in  us,  on  us,  and  about  us  everywhere.  The  smuts,  rusts  and 
mushrooms  are  larger  and  more  easily  seen.  Many  of  these  are, 
however,  quite  destructive  to  our  crops  and  are  of  special  interest 
to  the  farmer.  "What  are  called  Imperfect  Fungi  are  not  de- 
fective in  themselves,  but  are  healthy,  active  organisms,  as  every 
gardener  knows,  from  the  attacks  they  make  on  his  plants.  Leaf 
spot  on  roses,  beets  and  beans,  scab  on  apples,  rot  in  tomatoes, 
and  mildews,  are  common  in  the  orchard  and  garden.  Their  life 
histories  have  not  been  as  thoroughly  studied  as  some  of  the  other 
classes.  After  the  Fungi  come  the  Algae.  Some  of  the  smaller 
species  of  this  group  can  swim  as  gracefully  as  a  fish.  People 
who  have  always  considered  a  plant  to  be  something  with  roots, 
stem  and  leaves,  that  grows  out  of  the  ground,  will  be  surprised 
when  they  see  the  gyrations  of  some  of  these  minute  organisms. 
We  have  placed  the  lichens  at  the  end  of  the  group  for  they

seem  to  be  a  happy  blending  of  Alga?  and  Fungi  into  a  mutual 
copartnership,  each  working  for  the  benefit  of  the  other.     • 

I  have  followed  Prof.  T.  IT.  Macbride  in  the  arrangement  of 
the  Slime  Moulds;  Prof.  F.  D.  Chester  in  Bacteria;  Ellis  and 
Everhart  in  Pj^renomycetes ;  and  Britton's  Mam  ml  in  the 
Pteridophytes  and  Spermaphytes.  We  obtained  much  of  the 
material  for  the  bulletin  from  "Contributions  to  the  Flora  of 
Iowa,"  by  Dr.  J.  C.  Arthur,  published  in  1876;  "Bulletin  of  the 
Agricultural  College,"  by  Dr.  C.  E.  Bussey,  1884;  "Proceedings 
of  the  Iowa  Academy  of  Sciences ; "  "  Proceedings  of  the  Daven- 
port Academy  of  Natural  Sciences;"  "Bulletins  of  the  Labora- 
tories of  Natural  History  of  the  State  University ; "  "  Reports  of 
the  Iowa  Geological  Survey, ' '  and  its  ' '  Bulletin  on  Grasses, ' '  and 
from  the  "Journal  of  Micology. " 

I  wish  to  express  my  gratitude  to  the  botanists  of  the  state 
for  their  pains-taking  and  unselfish  labor  in  publishing  the 
names  of  plants  they  have  found  growing  in  the  state,  and  my 
obligation  to  them  for  material  used  in  compiling  this  bulletin: 
To  Prof.  T.  H.  Macbride  for  the  list  of  Slime  Moulds  and  Mush- 
rooms ;  to  Harriet  Vandivert,  Alice  W.  Hess  and  Nora  Allen  for 
lists  of  Basidiomycetes ;  to  F.  J.  Seavers  for  list  of  Dis- 
comycetes;  to  Prof.  B.  Shimek  for  Liverworts;  to  Prof.  T.  E. 
Savage  for  Mosses;  to  Prof.  B.  Fink  and  R.  E.  Buchanan  for 
Algae ;  to  H.  S.  Hitchcock  for  Peronosporere ;  to  Dr.  Henry  Albert 
and  R.  E.  Buchanan  for  Bacteria;  to  Prof.  Bruce  Fink  and  Kate 
Miller  for  Lichens,  and  to  Prof.  L.  H.  Pammel  for  list  of  Grasses 
and  Fungi.  For  County  Floras  that  have  been  used,  I  wish  to 
express  my  thanks  to  C.  R.  Ball,  E.  M.  Olsen,  M.  P.  Somes,  -M.  B. 
Peck,  H.  A.  Mueller,  R.  J.  Cratty,  T.  J.  Fitzpatrick,  M.  J.  Fitz- 
patrick,  W.  D.  Barnes,  Fred  Rupert,  A.  A.  Miller,  J.  E.  Gow, 
J.  P.  Anderson,  C.  M.  King,  and  many  others  whose  work  has 
been  examined  and  checked  in  preparing  this  bulletin. 

Many  changes  have  been  made  in  classification  of  species  in 
recent  years.  I  have  not  always  taken  kindly  to  sonir  of  these 
changes.  The  names  learned  from  Gray's  and  Wood's  Manuals 
more  than  thirty  years  ago  still  have  a  warm  place  in  our 
memory.  We  will  probably  continue  to  say  Ampelopsis  instead 
of  Parthenocissus,  in  speaking    of    the    Virginia  creeper,   and 


6  STATE    HORTICULTURAL    SOCIETY 

Nymphcea  sounds  better  to  my  ears  than  Castalia  for  our  sweet- 
scented  White  Water  Lily. 

There  are  many  other  changes  like  these  in  this  list,  that  we 
do  not  like  to  make,  but  believe  it  best  to  do  so,  rather  than  fol- 
low my  opinion,  as  it  makes  it  easier  for  the  student  who  is  using 
the  manual  of  one  author,  to  get  the  synonyms,  than  to  follow 
different  authors  on  the  same  subject.  We  have  also  aban- 
doned the  use  of  capital  letters  for  species.  This  I  believe  is  a 
move  in  the  right  direction,  for  it  gives  a  better  form  than  to  use 
capitals  when  the  name  of  a  person,  country  or  substantive  is 
given  to  a  species. 

This  bulletin  has  been  written  in  the  hope  it  might  prove 
helpful  to  the  young  people  who  are  anxious  to  learn  the  names 
of  the  plants,  many  of  which  they  see  daily  while  working  on  the 
farm  or  strolling  through  the  woodlands  of  the  state.
